On receipt I have the battery inserted into the Nikon charger and found that it runs harder than the original battery. When I then used it in the camera, which was good, but he was only with great difficulty and after trying numerous aids removed. After I had finally managed to pfriemeln the battery from the camera, I have the plastic seams filed with an emery board - since it goes well, glides almost like the original in the camera shaft and can be removed easily. From a performance point I can not tell the difference from the original. After the reviews I had read before buying, it took me astounded that such a post was necessary.
